During his birthday celebration, Minister of Personnel Li Tingfu is deeply impressed by the intelligence and character of the young scholar Wang Yulin. He immediately offers his beloved daughter Li Xiuying in marriage.

However, Xiuying’s cousin Gu Wenyou, who has long coveted her, becomes consumed by jealousy upon learning of the engagement. Working together with a scheming matchmaker, he manipulates Xiuying’s maid into stealing her treasured family heirloom—the Jade Hairpin—and forges a secret love letter. Both are planted in the bridal chamber to frame Xiuying for infidelity.

On their wedding night, Wang Yulin discovers the fabricated evidence and believes the accusation without question. Heartbroken and enraged, he subjects his innocent wife to relentless coldness and emotional cruelty. Unable to understand the cause of his hostility, Xiuying silently endures her suffering in order to preserve family harmony and fulfil her duties as a devoted wife.

As the years of emotional torment take their toll, Xiuying falls gravely ill. When her parents learn of her condition, they confront Wang Yulin. Only then does he reveal the hairpin and the forged letter. After a thorough investigation, the conspiracy is finally uncovered, Gu Wenyou’s deception is exposed, and the truth comes to light.

Overcome with remorse, Wang Yulin begs Xiuying’s forgiveness. She chooses compassion over resentment, and the couple are finally reconciled.
